As you may remember, I had a similar problem with my 96 900SE. I considered various possibilities, including a defective gas cap or a worn-out oxygen sensor. The Saab dealer replaced the sensor on a trial basis, but the light came back on again after a few days. When the new oxygen sensor did not cure the problem permanently, I took the car back. They put my old oxygen sensor back in, since apparently that was not the source of the problem. Now, they seem to have fixed the problem permanently (although I can hardly say that without feeling that I am tempting fate). They did something that shows up on the bill as "checked ECM, R+R harness, and solder crimp connection." Cost $234. By the way, is it not possible to reset the system by removing the appropriate fuse for a while? Wouldn't that have the same effect as disconnecting the battery?
